Plutopia: Nuclear Families, Atomic Cities, and the Great Soviet and American Plutonium Disasters is a 2013 book by American environmental historian Kate Brown.The book is a comparative history of the cities of Richland, in the northwest United States adjacent to the U.S. Department of Energy Hanford Site plutonium production area, and Ozersk, in Russia's southern Ural mountain region.

The reactor is part of the final step for a plutonium-burner core (a core designed to burn and, in the process, destroy, and recover energy from, plutonium) [4] The plant reached its full power production in August 2016. [5] According to Russian business journal Kommersant, the BN-800 project cost 140.6 billion rubles (roughly 2.17 billion ...
The US has about 90 tons of weapons-capable plutonium, while Russia has 128 tons. [1] The US declared 60 tons as excess, while Russia declared 50 tons excess. [1] The two sides agreed that each would eliminate 34 tons. [1] The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity. [2]
However, plutonium(IV) oxide containing a natural abundance of oxygen emits neutrons at the rate of roughly 2.3 × 10 3 n/sec/g of plutonium-238. This emission rate is relatively high compared to the neutron emission rate of plutonium-238 metal. The metal containing no light element impurities emits roughly 2.8 × 10 3 n/sec/g of plutonium-238 ...
The design did not include an internal combustion engine; rather, the vehicle was to be powered by a small nuclear reactor at its rear, based on the assumption that nuclear reactors would eventually become small enough to make this possible. The car was to use a steam engine powered by uranium fission, similar to those found in nuclear ...
To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
Plutonium oxide is substantially more toxic than uranium oxide, making fuel manufacture more difficult and expensive. As plutonium isotopes absorb more neutrons than uranium fuels, reactor control systems may need modification. MOX fuel tends to run hotter because of lower thermal conductivity, which may be an issue in some reactor designs.
